17W + 17W Class D Speaker Amplifier for Digital Input - BD28623MUV

BD28623MUV is a Class D Speaker Amplifier designed for Flat-panel TVs in particular for space-saving and low-power consumption. This IC delivers an output power of 20W + 20W. This IC employs state-of-the-art Bipolar, CMOS, and DMOS (BCD) process technology. With this technology, the IC can achieve high efficiency. In addition, the IC is packaged in a compact back-surface heat-sink type power package to achieve low power consumption and low heat generation and to eliminate need for external heat-sink. With this package, total output power is only 34W as compared to 40W total output power of package with external heat-sink This product satisfies all needs for drastic downsizing, low-profile structures and powerful high quality playback of sound systems.

Output Feedback Circuitry which prevents decreaseof sound quality caused by change of power supplyvoltage, achieves low noise and low distortion,So the large electrolytic-capacitors for VCCbypass is able to be eliminated.
